Directions

Preheat grill to 450F.

Pat steak dry. Stir together 1 teaspoon salt, cumin, coriander, and pepper in a small bowl and rub mixture onto both sides of steak. Grill steak 6 minutes per side for medium-rare. Transfer to a cutting board and let stand 5 minutes.

While the steak is cooking, make the chimichurri. In the bowl of a food processor, add the garlic, cilantro, parsley, vinegar, oil, cayenne, and remaining 1/2 teaspoon salt, then pulse until herbs are finely chopped and a smooth sauce is formed.
